TIRE-VALVE-STEM PROTECTOR.

To all whom it may concern:

Be it known that I, CHARLES W. LURTEY, a citizen of the United States,residing at Little Rock, inthe county of Pulaski and- State of Arkansas,have invented a new an'd useful Tire-Valve-Stem Protector, of which thefollowing is a specification.

This invention relates to means for protecting the valve stems frombeing c ut or torn oi in case the tire creeps on the rim of the wheel.Itis a well known fact that tires often become loose on the rim, andconsequently move with respect thereto. As the valve stems ass throughopenings in the wheelrims, t e result is that the stems are cut,allowing the escape of air, and necessitating repairs to the t1re. j

The principal object of the present case is to provide a novel andexceedingly simple article of manufacture that may be employed inconnection with .the ordinary tire and valve stem, .and will, to a verymaterial degree, reduce the danger of cutting the same,

` incase the tire creeps upon the rim.

The preferred embodiment of the invention is illustrated in theaccompanying drawings, whereinz- Figure l'is'a longitudinal sectionalview,

through a portion of a tire and wheel rim, showing the improved rotectorin place. Fig. 2 is a cross sectiona view of the same. Fig. 3 is adetail perspective view of said protector. I

glhe wheel rim and tire may be of any ordinary or desired construction,a portion of the rim being illustrated at 4, and vhaving' a peripheralgroove 5, in which the tire is seated. In the present embodiment, thetire comprises an outer casing or section and an inner tube or section7, the latter carrying a valve stem 8, containing the usual valvemechanism. This valve stem projects through the outer casing orsectionand through t rim 4 of the wheel, as shown.

The protector comprises a base plate 9 transversely and longitudinallycurved to conform to the contour of the tire, and having an open endedsleeve'lO, projecting from its central portion. The base plate 9 islocated between the casing and tube or sections of the tire, and may beeither loosely Specification of Letters Patent. Application filed May15| 1906- ASerial No. 316,900.

arranged Vtherein. or suitably vulcanized thereto. The sleeve 10projects from the inner casing, and surrounds the valve stem,

vsaid sleeve also passing through the rim 4.

It is to be understood that this sleeve does not constitute a part ofsaid-valve stem; but.

is an entirely independent velement in the form of a casing that is thussecured to the tire and incloses the stem. 1

With arrangement, it will be seen that in case'the tire creeps, insteadof the flexible valve stem tube coming into contact with the rim of' thewheel, the metallic casing or sleeve surrounding the same acts as aguard, and the friction is thus broughtv against the protector, insteadof the valve stem. It will of course be understood that the saidprotector may be constructed of any desired material, preferablysuitable metal, and it will be evident by reference to Fig. 3, that itmay be easily and cheaply manufactured. Moreover, it may be employed inconnection with tires of diHerent characters, and readily ap lied tothose now in use.

rom the Jforegoing, itis thought that the construction, operation, and'many advantages of the herein described invention, will be a parent tothose skilled in the art, without rther description, and it will be'understood that various changes in the size, shape, proportion, andminor details of construction, may be resorted to without departing fromthe spirit or sacriiicing any of the advantages of the invention.

-Having thusully described my invention,

what I claim as new, and desire to secure by Letters Patent, is

The combination w1th`a tire having inner and outer sections, of a valvestem and valve mechanism projecting Jfrom the tire, and av stemprotector comprising a base plate that isv located between the tiresections, said -plate being longitudinally and transversely curved, andan o en ended sleeve projecting from the base p ate and from the tireand surrounding the projecting portion of the valve stem. y

In testimony, that I `claim, the fpregoing as my own, I have heretoai'lixed my signature .in the presence of two witnesses.
